Pathophysiology Final Exam

1. A nurse caring for a patient with a diagnosis of lung cancer is aware that the primary risk factor for developing lung cancer is:

A. Alcohol consumption
B. Smoking
C. Poor diet
D. Environmental exposure

Correct answer: B

Rationale: The correct answer is B: Smoking. Smoking is the primary risk factor for developing lung cancer. Tobacco smoke contains numerous carcinogens that can damage the cells in the lungs, leading to the development of cancer. Alcohol consumption (Choice A), poor diet (Choice C), and environmental exposure (Choice D) can contribute to overall health risks, but they are not the primary risk factors specifically associated with the development of lung cancer.

2. A child with a serious fungal infection is receiving amphotericin B parenterally. Which of the following minerals will the patient most likely be required to receive?

A. Chloride
B. Magnesium
C. Glucose
D. Sodium

Correct answer: B

Rationale: When a patient is receiving amphotericin B, which is known to cause renal toxicity, they are most likely to require magnesium supplementation. Amphotericin B can lead to renal loss of magnesium, potassium, and calcium. Magnesium is an essential mineral that plays a vital role in various physiological functions, and its levels need to be monitored and supplemented when necessary. Chloride, glucose, and sodium are not typically supplemented in the context of amphotericin B therapy for a serious fungal infection.

3. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse teach the patient about the use of this medication?

A. Medroxyprogesterone should be taken with food to prevent nausea.
B. Medroxyprogesterone can be taken intermittently when symptoms worsen.
C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
D. Medroxyprogesterone should be discontinued if side effects occur.

Correct answer: C

Rationale: The correct answer is C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Taking it at different times can lead to hormonal fluctuations and reduced medication efficacy. Choice A is incorrect because medroxyprogesterone does not need to be taken with food to prevent nausea. Choice B is incorrect as medroxyprogesterone is typically taken continuously rather than intermittently. Choice D is incorrect because side effects should be reported to the healthcare provider for further evaluation and management, not automatically leading to discontinuation of the medication.

4. Which of the following are signs and symptoms of myocardial infarction?

A. Persistent chest pain which may radiate to the arm
B. Brief sternal chest pain on inspiration
C. Rapid respirations with left-sided weakness and numbness
D. Left upper quadrant abdominal pain which radiates to the back and shoulder

Correct answer: A

Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.

5. Seizures are diagnosed by which of the following?

A. Electroencephalogram (EEG) and ECG
B. Seizure symptoms and complete blood count (CBC)
C. Seizure symptoms and electrocardiogram (ECG)
D. Seizure symptoms and EEG

Correct answer: D

Rationale: Seizures are most accurately diagnosed by EEG, which measures brain activity. Choice A is incorrect as ECG (electrocardiogram) measures heart activity, not brain activity. Choice B is incorrect as CBC (complete blood count) is a blood test and not used to diagnose seizures. Choice C is incorrect as an ECG (electrocardiogram) also measures heart activity, not brain activity, and is not the primary diagnostic tool for seizures.
